runtime(rst): Add support for rst_minlines
Following the approach used in other syntax definitions, add support for
defining the "syntax sync minlines=..." values for rst files in the
users' ~/.vimrc files, to allow the users to adjust that value in case
syntax highlighting stops working for some of the files they edit.
